Release Notes¶

0.5.0¶

LensKit 0.5.0 modifies the algorithm APIs to follow the SciKit design patterns instead of our previous custom patterns. Highlights of this change:

Algorithms are trained in-place — we no longer have distinct model objects.
Model data is stored as attributes on the algorithm object that end in _.
Instead of writing model = algo.train_model(ratings), call algo.fit(ratings).

We also have some new capabilities:

A number of improvements, including replacing Cython/OpenMP with Numba and adding ALS.

A lot of fixes to get ready for RecSys.
